An Andalusian team of researchers led by the University of Granada has demonstrated the efficacy of a new drug against cancerogenic stem cells, which cause the onset and development of cancer, of relapse after chemotherapy and metastasis. This drug, called Bozepinib, has proved to be effective in tests with mice. The results have been published in the prestigious journal Oncotarget.

Cancerogenic stem cells appear in small quantities in tumours, and one of their important features is that they contribute to the formation of metastasis in different places within the original tumour. Cancerogenic stem cells remain dormant under normal conditions (i.e. they do not divide). Conventional chemotherapy and radiotherapy act upon those cancer cells which are clearly differentiated—i.e. which are undergoing processes of division—but they cannot destroy these dormant cancerogenic stem cells. Actually, after a positive initial response to treatment, many cancer patients suffer a relapse because these cancerogenic stem cells have not been destroyed.
